Experimental evaluation of magnetic anisotropy based on magnetic Barkhausen noise
摘 要
将磁巴克豪森噪声技术应用于典型材料的磁各向异性评估中,确定影响其易磁化轴和磁各向异性程度的因素。通过论述影响磁各向异性的3种机制,将磁巴克豪森噪声包络曲线划分为不同的磁化区段。构建多角度磁巴克豪森噪声试验系统,对4种典型材料进行了试验,得到了不同磁化阶段、不同特征参量的极图。通过对比研究,分析励磁频率、励磁电流以及不同磁化区段对磁各向异性结果的影响。结果表明:不同磁化区段提取的特征参数可以反映不同机制引起的磁各向异性,适用于磁各向异性研究的每种材料的检测参数都存在差异。
Abstract
The magnetic Barkhausen noise technology is applied to the evaluation of the magnetic anisotropy of typical materials, and the factors that affect the magnetic easy axis and the degree of magnetic anisotropy are determined. By discussing the three mechanisms affecting the magnetic anisotropy, the magnetic Barkhausen noise envelope curve is divided into different magnetization sections. A multi-angle magnetic Barkhausen noise experimental test system was constructed, experiments were performed on 4 typical materials, and pole figures with different magnetization stages and different characteristic parameters were obtained. Comparative studies were conducted to analyze the influence of excitation frequency, excitation current and different magnetization sections on the results of magnetic anisotropy. The results show that the characteristic parameters extracted from different magnetized sections can reflect the magnetic anisotropy caused by different mechanisms, and the detection parameters suitable for the study of magnetic anisotropy are different for each material.
